The air cooling device is ordinarily installed on a roof of a server room, has a heat exchanger and a fan therein and is used to cool a server rack in the server room where computers are housed, in such a way that air is sucked from an inlet on a bottom surface, cooled through the heat exchanger and blown out from through an outlet on a front surface by the fan. 

We claim the ornamental design for an air cooling device, as shown.
